A Study to Evaluate Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Multiple Doses of Natalizumab (BG00002) Administered Subcutaneously to Japanese Participants With Relapsing-Remitting Multiple Sclerosis

Summary

The primary objective of this study is to evaluate the efficacy of natalizumab 300 milligrams (mg) subcutaneous (SC) every 4 weeks (Q4W) administrations up to 24 weeks in Japanese participants with relapsing-remitting multiple sclerosis (RRMS). The secondary objectives of the study are to evaluate other clinical and magnetic resonance imaging (MRI) measures of efficacy of natalizumab 300 mg SC Q4W administrations in Japanese participants with RRMS, to evaluate the safety, tolerability, and immunogenicity of natalizumab 300 mg SC Q4W administrations up to 48 weeks in Japanese participants with RRMS, to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of natalizumab 300 mg SC Q4W administrations up to 24 weeks and for an additional 24 weeks in Japanese participants with RRMS.
